No, just load one of our basemaps out of the PC Link basemap folder.
Note before you "overwrite it" I suggest that you save a copy of the existing protected map as you can always load that back in if you get stuck. Also before overwriting, have a look at the runtimes screen and note down (or take screenshots) what functions are assigned to aux outputs, analog inputs, and DI's like pictured below. Having this info will make it easier to set up the new map.
